Avalanche on Mt. Tallac above Lake Tahoe 1,000 feet long, 150 feet wide

The Sierra Avalanche Center is reporting a large (D4) slide that appeared to run during the rain on Monday, February 21 in Desolation Wilderness on the slopes of Mt. Tallac above Lake Tahoe.

The 1,000 foot long avalanche named Corkscrew Slide Path, started at an elevation of 6800 feet and was approximately 150 feet wide. Trees up to approximately 6 inches in diameter were visible within the debris at the end of the slide.

According to the center, the bottom 500 feet of the slide were clearly visible under the new snow,and the next few hundred feet became much faint, with the top impossible to discern under the new snow.

"Interesting to note that despite the large size of this slide, it only occupied a small portion of the historical slide path and deposition zone," Sierra Avalanche Center posted on their website.

Warmer and wetter storms this winter have created several avalanche warnings for the Sierra Nevada.

There were a few other reported avalanches this week. On Thursday, snowboarders triggered a 500 foot long avalanche above lower Angora Lake that was 500 feet long and 75 feet wide.
